qtCreator wont compile Hello World Program

I downloaded the whole qtSDK and installed it. Then i launched the qtCreator and try to run the Hello-World-Program as a qt console application. It didnt compile and said that it couldnt find "cl". So I researched on the internet and made a batch file containing

Code:

---

SET PATH=%PATH%;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin
start C:\QtSDK\QtCreator\bin\qtcreator.exe

---

That fixed the error about the missing "cl"-file, but the jom.exe still exits with code 2 and doesnt compile:

Code:

---

jom 1.0.6 - empower your cores
 
command failed with exit code 2
command failed with exit code 2
command failed with exit code 2
12:30:35: The process "C:\QtSDK\QtCreator\bin\jom.exe" exited with code 2.
Error while building project Hello2 (target: Desktop)
When executing build step 'Make'

I hope you can help me.

PS: My program code looks like this, but i doubt, thats the problem:

Code:

---

#include <QtCore/QCoreApplication>
 
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
 
    return a.exec();
}

I have installed VS 2010 Express Edition and am using Windows 7 64 bit OS.

I guess you are posting here what appers in the Build Issues window. You should see what happens in the Compile Output window to get a clue about what jom is trying to do but fails trying.

No, actually that is the Compile Output. Here is the complete one:

Now, that I read it: my Windows username consists of two words divided by a space and contains special characters (like "ü"). Could this cause the problem?

I made it finally work now by additionally downloading the Qt4.8.0 for Mingw and using this compiler instead of the VC one.
